MALWARE: Ragnar Locker

A new ransomware attack method takes defense evasion to a new level—deploying as a full virtual machine on each targeted device to hide the ransomware from view. In a recently detected attack, Ragnar Locker ransomware was deployed inside an Oracle VirtualBox Windows XP virtual machine. The attack payload was a 122 MB installer with a 282 MB virtual image inside—all to conceal a 49 kB ransomware executable.
